.To all whom t may concern Be it known' that we, VALTERC. KiLrUs andJorrN F. RUDOLPH, citizens of the'UnitedStates, residing'at Lompoc, inthe county of Santa' Barbara and State ofiCalifornia,

have invented a certain' new and: 'useful' Thermocontainer, of which the followingis a specification.

Our' inventionrelatesr to thermo containers, particularly to'tliermo bottles, andthe objects of ourinventionare': first, to provide a novel andeiii'cientthermo container which will"keepproductscold` or Ahot as desired; second,` to'provide a thermo container which cannot easily' be distortedA orbrokenk by slight impact orV by dropping the same;

third, to provideV a container of"k this class with'ainovel'andhighly efficient heat insulating means; fourth, to provide a container of Vthis 'class in which the insulating medium supports the-container and* casing Vmembers relatively and rigidly with each other; fifth, to providel axcontainerof this class inwhich the cover forccstheY stopper into the neck of the container and holds the stopper in said position while the coveris in place; sixth, to provide a novelly constructed thermo containerl andone, in which vthe cas-v ingk thereof is readily separableU forL replace ing the"innercontainer,` andzseventh, tol provide a container' of this class which is very simple and economical of'y construction,- particularly durable, efficient andwhich-willnot readily deteriorate or lget out` ofv order.

Vith these' andV other objects in View as will appear hereinafter our invention con-y sists ofcertain novel features ofconstruction, lcombination and arrangement: ofi parts and portions as willbe hereinafter described in detail and particularly'set forthvin the appended claims', reference being hadto ythe accompanying` drawings and to the characters of reference thereon which form a part ofl thisv application, in which:

Figure'lis a planview of our thermo containerA with the coverv thereof partially brokeny away; Fig. 2` isv an elevational v-iew thereof showing4 certain parts'and portions broken away. andv in section to facilitate". the illustration;` Fig. 3, is a fragmentaryL sectional viewV thereof taken through` 3-3 of Fig. 2; Fig. t' is a plan viewof' Va slightly modified form of'co'nstruction ofour thermo container with the cover thereof shown fragn mentarily andFig. 5 is side celevational viewthereof showing lcertain parts and portions biok'enaway and in section to facilitate the illustration.l f

Like characters of reference refer tosimilar parts andlportions throughout the several: viewsof the drawings.

The `upperl casing member l, lower casingy member 2, rein-forcing tie rod lmembers 3, container 4, gasket 5, insulating materiale, stopper 7 vvand' the cover '8' constitute the l,prin cipal f parts and'lpo'rtions ,of our thermov containerV inf its preferred form.

The upper casi-ng member 1 islprefe'rablycylindrical in 'shape'andf proVi'ded-at its upperend-v with acoveriportionl integrallysecured to the cylindrical portion of the member l; Said cover-portion' la is provided with a centrallopening lb andwitha' downwardly extending annular flangeportion 1F contiguous to said opening therein. The lowercasing/member 2 is providedv with an inwardly extending flange portion 2 which extends intoandengages the inner-side of the cylindrical'portion ofthe memberV l, positioningthe members 'l' and2 laterally with each other. Saidca-singmembers hand-2 are secured together bythe =reinforcingand tie rod members 3 in the form of boltswhich Y extend' through lugs ld providedn atuthe upper end ofthe casing lmember l vand l similar guide/lugsl 1*'atthe lower* portion offthe casingmem-ber 1 and' into the lir'ite'rnally threaded lugs Qbfwhi'chextendVouwardly from the lower casing member 2; The container-4 is preferably made'of glass and is provided at theupperouter portion of its neck with an annular groove 4C for the vreception ofthe annular'iange lc ofi the casinggmember l', which flangeis adaptedto vposition the container 4' laterally within the casing l. A

gasket 5, preferably ymade vof cork, is inter:

posed between the liiange portion of` the member` ll and the groove portion of the neck of thecontainer 4, toreducethe waste of heatby conductivity to av minimum.' A-n insulating material 6', whichconsi'sts preferably of` a dehydrateddiatomaceous product sometimes known as diatomaceous earth consisting"ofmicroscopic forms of diatoms or hollow"` cells.. This insulating material is ypacked in the'fspac'e between'the casing and containerv to prevent movementof the latter los "within the' formeri which. strengthens the container and casing against breakage or distortion, and has been found to be a highly efcient and economical insulating material for this purpose. The cover portion 1L is provided with an upwardly extending annular flange portion 1f intermediate its periphery and central opening and is provided on the periphery thereof with fragmentary portions of threads lg which are adapted to engage similar thread portions on the inner side of the Cover 8 which is held in position against the upper portion of the casing by said portions. Said cover is preferably made cup shape at its central portion to engage at its lower side the stopper 7 provided in the neck of the container 4L and hold said stopper in said position when screwed against the cover portion of the casing 1. A web 8b extends across the cup shaped portion of the cover 8 to facilitate the securing of the cover in position.

In the modified form of construction we have shown a similar casing 1, although with a slightly rounded upper portion and the reinforcing and tie rod members, eX- tending from the upper to the lower ends thereof, positioned within said casing against the wall thereof. The slightly offset portion at the upper end of the container as shown in Fig. 5 of the drawings in the modified form of construction is provided with similar fragmentary thread portions as previously described in connection with the preferred structure, which is adapted to engage similar thread portions on the inside of the cover 8, which cover in this modified form of construction is somewhat smaller than the structure previously described.

Though we have shown and described a particular construction, combination and arrangement of parts and portions and a certain modification thereof, we do not wish to be limited to this particular construction, combination and arrangement nor to the modification, but desire to include in the scopel of our invention the construction, combination and arrangement substantially as set forth in the appended claims.

It is obvious from the drawings and foregoing description that we have provided a thermo container which cannot easily be distorted or broken by slight impact or by dropping the same; that we have provided a container of this class with novel and highly etiicient heat insulating material; in which the insulating material supports the container and casing members relatively and rigidly with each other; in which the cover forces the stopper into the neck of the container and holds the stopper in said position while the cover is in place; that we have provided a novelly constructed container of this class and that we have pro- ?Tlde container of this class which is very simple and economical of construction, particularly durable, efiicient and which will not readily deteriorate or get out of order.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is:

l. A container of the class described, including a sectional casing, reinforcing and tie members extending the length of said casing securing said casing sections to each other and reinforcing said receptacles, a container positioned within said casing and a diatomaceous insulating material positioned in the space between the casing and said container positioning' the same relatively to each other.

2. A container of the class described, including a sectional casing provided with an opening in one end, reinforcing and tie members extending the length of said casing securing said casing sections to each other and reinforcing said casing, a container positioned withinV said casing with its opening contiguous to the opening of said casing, a diatomaceous insulating material positioned in the space between the casing and said container positioning the same relatively to each other, a loose heat insulating gasket interposed between the inside of said casing, contiguous to the opening therein, and said container and a stopper for said container.

3. A container of the class described, including a sectional casing provided with an opening in one end, reinforcing and tie members extending the length of said casing securing said casing sections to each other and reinforcing said casing, a container positioned within said casing with its opening contiguous to the opening of said casing, a diatomaceous insulating material positioned in the space between the casing and said container positioning the same relatively to each other, a loose heat insulating gasket interposed between the inside of said casing, contiguous to the opening therein, and said container, a yieldable stopper for said container and a cover positioned over the opening of said casing and secured to said casing adapted to engage the outer end of said stopper and force the same into said container when being secured to said casing.

4. A container of the class described, including a separable sectional casing provided with an opening in one end, reinforcing tie members separably securing said casing sections to each other, a container, provided with a similar opening loosely positioned within said casing with its opening contiguous to the opening of said casing, a diatomaceous heat insulating material positioned and packed in the space between the casing and said container positioning the saine relatively to each other, a heat insulating gasket loosely interposed between the inside of said casing and said container contiguous to their respective openings, a yieldable stopper for said container and a cover positioned over the opening of said casing and secured to said casing adapted to engage the outer end of said stoppei1 and force the same into the opening of said container When being secured to said casing.

5. A container of the class described, including a separable sectional casing provided With an opening in one end, tie-bolts screWably securing said casing sections together, a container, provided with an opening at one end, loosely positioned Within said sectional casing, and a heat insulating material contained in one of said casing sections and packed therein positioning said container relatively thereto, said heat Vinsulating material being packed therein with the securing of said casing sectionsvtogether. In testimony whereof, We have hereunto set our hands at Lompoc, California, this 22 day of September, 1922.
